Does this light give off a lot of heat? LEDs are the most efficient lights today. They produce so little heat that you can actually let the plant touch the light (though this is not recommended - since it reduces the size of your growing area).

The heat generated by the unit is absorbed by the heat sink and dissipated by the fans on the back of the lamp. How does the specific wavelength work? Blue(wavelength: 400nm 520nm): Help plants grow. Red(wavelength: 610nm 720nm): Help plants sprout and flowering , and is the key for flowering plants.
